When newspapers and radio describe the damage caused by a hurricane named Hazel,girls named Hazel are probably teased by their friends.To keep out of trouble,the Weather Bureau says,“Any resemblance between hurricane names and the names of particular girls is purely accidental.”
Some women became angry because hurricanes are given their names,but many other women are proud to see their names make headlines.They don’t even care that they are the names of destructive storms.Because more women seem to like it than dislike it,the Weather Bureau has decided to continue using girl’s names for hurricanes.
In some ways a hurricane is like a person.After it is born,it grows and develops,then becomes old and dies.Each hurricane has a character of its own.Each follows its own path through the world,and people remember it long after it gone.So it is natural to give hurricanes’ names,and to talk about them almost if they were alive.

A．They suffer from hurricanes.

B．The Weather Bureau look for them.

C．Others often make fun of them.

Geologists have been studying volcanoes for a long time.Though they have learned a great deal,they still have not discovered the cause of volcanic action.They know that the inside of the earth is very hot,but they are not sure exactly what causes the great heat.Some geologists have thought that the heat is caused by the great pressure of the earth’s outer layers.Or the heat may be left from the time when the earth was formed.During the last sixty years scientists have learned about radium,uranium,thorium,and other radioactive elements.Many scientists now believe that much of the heat inside the earth is produced by radioactive elements.
Whatever the cause of the heat may be,we do know that the earth gets hotter the farther down we dig.In deep mines and oil wells the temperatures rise about 1°F for every 50 feet.At this rate of the temperature 40 miles below the earth’s surface should be over 4 000°.This is much hotter than necessary to melt rock.However,the pressure of the rock above keeps most materials from melting at their usual melting points.Geologists believe that the rock deep in the earth may be plastic,or puttylike（油灰状的）.In other words,the rock yields slowly to pressure but is not liquid.But if some change in the earth’s crust releases the pressure,the rock melts.Then the hot,liquid rock can move up toward the surface.
The cause for the great heat inside of the earth is______.

A．great pressure of the earth’s outer layers

B．the heat left from the time when the earth was formed

C．radioactive elements giving out heat

D．not sure

According to the passage,______ prevents most rock from melting at its usual melting points.

A．the pressure of the rock itself

B．the pressure of the rock above

C．the pressure of the earth’s outer layers

D．the heat given out by some radioactive elements

According to the passage,which of the following is NOT true?

A．The farther down,the hotter the earth gets.

B．The rock deep in the earth is liquid.

C．When the pressure releases from the earth’s crust,the rock melts.

D．Rock would be melted at 4 000°.

An Announcement
It was a small town which lay by the coast.Most people there lived by catching fish.The hurricanes often struck the area from July to October.Some of the people died on the sea when their boats were blown over by the high winds.So they paid much attention to the weather forecasts.They were afraid to meet with the hurricanes when they were catching fish on the sea.Each of the families had a radio and people always took them with themselves and listened to them at any time.

On the fourth day they read an announcement（通告）on the Town Weekly.It was written,“Recently we have to stop the weather forecast because of the bad weather.We usually get the forecasts from the airport.But the roads are all blocked by the fallen trees and stones.Whether or not we’ll be able to broadcast the weather forecast tomorrow depends on the weather！”
